This invention relates to an improved rail coupling and seeks, among other objects, to provide a device of this character employing means for limiting the parts of the coupling against longitudinal separation in either 1 direction. I J

Another object of the invention is to provide a rail coupling which will completely surround the meeting end portions of the rails and effectually brace sald railsiat said meet-' g 12 1n reverse relation to the recesses and ing end portions.

' A further object of the invention is to pro- .vide a rail coupling which will be easy to install and, which will need no further attention after installation. Other and incidental objects of the invention not specifically mentioned iirthe foregoing will appear during the course of the following description.

In the drawings: Figure 1 is a perspective view of the device in position. 7

Figure 2 is a fragmentary bottom plan view of the device.

Figure 3 is a vertical sectional view of the device on the line 3+3 of Figure 2, looking in the direction indicated by the arrows.

Figure 4: is an enlarged fragmentary perspective, view showing in more detail the mating interlocking scarf joint construction employed between the sections of the'coupling. Referring now more particularly to the ac companying drawings, thenumeral 1 indicates in general the meeting end portions of 55 conventional railroad rails.

' The improved rail coupling forming the subject matter of the present invention comprises companion chair plate sections 2 and 3 having relatively thick bottom plate sections Al and 4 seating the base flanges of the rail ends, andside plates or portions 5 abutting the webs ofthe rails andenga'ging under the threads" thereof. Connecting the bottom plate sections with the side plates are flange engaging portions 6' which cooperate with the bottom plate sectionsto snuglyreceive the flange portions of the meeting ends of the rails 1. 7 Y i As may be seen more clearly in Figures 2 t0 and 4c of the drawings, the ends of the bot- Y ders 10.

Bolts. 15 are then passed through the side portions 5 and the webs of the rails and tightened, whereby the parts will be firmly held in assembled relation.

Having thus described the invention, we 'claim'zw I i A railroad rail coupling including companion chair plate sections having mating bottom plate sections, one of said bottom plate sections being cut away at its ends medially of its thickness, one end from the top and the other end from the bottom, to provide recesses having stepped shoulders and the remaining portion of the thickness extendedvto form stepped scarf tongues, the other of the bottom 7 plate sections being provided With identical tongues and recesses adapted to cooperate t with the tongues and recesses onthe first mentioned bottomplate section but disposed in' reverse relationthereto whereby the sections 7 will bejllimitedagainst' longitudinal sepam-v tive verticaimovementr tion in either direction as Well asagainst rela- In testimony wh reo efi zi u sigma; tures. i
